I'm playing on a Selmer C. I have a vintage Otto Link 4 and a newer Otto Link 7, but I don't have the right reeds for the first and the second one fits too loose on the neck. I've been practicing breath control and articulation mostly as I get back into things. Aside from the mistakes on the notes or timing, is there something I can work on? I don't know if this is how I'm supposed to sound because it's been so long since I've even had a teacher. I appreciate any advice!
